Be it known that LHAnvnr M. SMITH, a citizen of the United States. residing at Mooresrille in the county of Morgan and State of Indiana, have invented a new and useful Explosive-Mixture Heater and Diluter, of which the following is a specification, reference being had to the accompanying drawings and to theletters and figures of reference marked thereon.

This invention relates to explosion. engines using carburetcd air as explosive mixture, the invention having reference more particularly to means for priming the engine in advance of the operation of the carburetor, and for heating and diluting the explosive mixture after the engine is in operation. Y

An object of the invention is to' providev in improved means whereby an explosion engine may be primed most economically, especially such as have an intake manifold supplying a plurality ,of cylinders with fuel.

A. further object is to providciinproved priming apparatus that shall be so constructed that the priming medium. shall be delivered as closely as possible to the explosion chambers and in the most effective condition.

A still further object is to provide im proved means for heating and diluting the explosive mixture during operation of the engine in order to attain economy of fuel in operation.

'55 Another object of the invention is to provide apparatus of the above mentioned character that shall be so constructed as to be adapted to be readily applied to automobiles now in use.

40 With the above mentioned and other objects in view, the invention consists in a plu rality of controlling valves adapted to be connected to the branches of an intake manifold, devices for simultaneously operating thevalves, a plurality of warm-air pipes connected respectively to the controlling valves and adapted to be Wound about the exhaust manifold of an explosion engine, two. reservoirs for carrying. and feeding to combustible liquid, and two feed pipes connected respectively to the reservoirs and to the Warm-air pipes in a novel manner, the warm-air pipes having novel forms.

The invention consists also in the novel 35 partsend in the combinations and arrang -A Referring to the drawings, Figure l: is a fragmentary perspective View of a four-cylinder explosion engine and portions of an ac automobile to which the improvement is applied; 2 is a rear elevation of the en'- gine and the Warm-air pipes connected therewith; Fig. 3 is a fragmentary vertical section or" the intake manifold and control- 655 ling valves connected therewith; Fig. e is a vertical section of one of the controlling valves in closed position on the line A A in Fig. 8 slightly enlarged; Fig. 5 is a section of the controlling valve on the line A.

Similar reference characters in the dir'l'erent figures of the drawings indicate corresponding elements or features of construction herein referred to. an

The explosion engine to which the inven tion is applicable may comprise one or more cylinders and. a suitable number of intake pipes or manifold branches and the exhaust manifold may be variously arranged, it beno ing designed to independently supply each intake pipe or manifold branch either With priming medium for starting the engine or Warm air for inereasin the eiiiciency of the explosive mixture commonly supplied for the cylinders after. starting the engine. it is further designed that the apparatus may be adapted for supplying the priming" medium to only one of the intake pipes. or manifold branches if desired in order to conserve the supply of the priming liquid,

such as gasolene.

The invention is comprehensively illustrated in connection with a four-cylinder engine and an automobile, the latter comprising a frame '1 and a. dash-board 2, the engine comprising Water jacketed. cylinders 3 and 4 cast together and companion cylinders 5 and 6 cast together the cylinders being mounted upon an engine frame 7. The

with an operating arm 18 to which is con-.

nected a rod 19 extending through the dashboard so as. to be reached by the operator. The exhaust manifold comprises a main pipe 20 having branches 21 and 22 connected with the exhaust valve chests 10 and 11 respectively. l

The improved apparatus as preferably constructed comprises a suitable number of controlling valves, there being two in the present case, and provided with connecting nipples 23 and 23 having coupling nuts 24: and 24 thereon respectively whereby valve bodies 25 and 26 are detachably connected to the nipples respectively, "one nipple being connected to the branch 13 and the other to the branch 14 of the intake manifold. The controlling valves are preferably of the stop cock type and comprise rotary plugs 27 and 28 mounted in the bodies 25 and 2-6 respectively and provided with operating arms 29 and 30 respectively to which a coupling rod 31 is connected for operating the plugs in unison, an operating rod 32 being connected to the coupling rod and extending through the dash-board 2 so as to be reached by the operator. The controlling valves are arranged as closely as may be convenient to the intake valve chests so that the heated explosive mixture is not liable to become cooled before reaching the explosion chest. Two warm-air pipes are connected to the two controlling valves respectively and preferably they are composed of annealed copper so that they may be bent as may be desired. One of the warm-air pipes is bent so as to form an upright portion 33 that is connected to the valve body 25, the pipe being bent so as to extend over laterally and downward and to form an arched portion 34 and a relatively lower portion 35 to which a pipe T 36 is connected. Another piece of' pipe is so bent as to be arched and its lower end portion 37 is connected to the T from which the pipe extendsupward so as to have a relatively high portion 38 from which a reach porticfi 39 extends to the position of the exhaust manifold around which the pipe is bent-in the form of a coil 40, the terminal end 41 of which is brought nearly to the valve chest 10 so as to constitute the inlet end of the; warm-airpipe to receive heated surface of the engine.

The

other warm-air pipe is somewhat similarly formed to constitute an upright portion 42 which is connected to the valve body 26 and is bent to form an arch 43 and a relatively low'portion 44 to which is connected a pipe T 45, another piece of pipe being bent to, form a relatively low portion 46 that is connected to the T, the pipe being arched to form a relatively high portion 47 from which extends a reach portion 458, the pipe being bent around the exhaust manifold 20 in the form of a coil 49 with its terminal end 50 broughtover nearly to the exhaust valve chest 11 to serve as the inlet end for heated air. The arched portions 38 and 4:7 and the reach portions of the pipes are brought together and protected against radiation of heat by a cover 51. It should be understood that the Ts are conveniently made use of for connecting feed pipes to the warm-air pipes at relatively low portions of the warm-air pipes but that separate T fittings obviously are not a necessity, since the feed pipes may be otherwise connected to the warm-air pipes.

Two reservoirs 52 and 53 are provided and are secured to the dash-board 2 at a suitable height to provide gravity feed, the bottom of each reservoir having a feed duct Set therein. A relatively small feed pipe 55 is connected preferably by means of a coupling nut 56 to the bottom of one of the reservoirs and is connected also to the T 45 by means of a nut 57, another feed pipe 58 being connected to the other one of the two reservoirs by means of a nut 59 and it is connected also to the T 36 by means of a nut 60, the coupling nuts being preferably employed so that the different parts may be conveniently shipped in knocked down condition. The interior of each reservoir has a screw-threaded bridge 61. Two valve stems 62 and 63 are provided for the respective reservoirs and each is screwed through the bridge 61 and has a needle pointed valve 64.

on its end that controls the duct 54:, the up per ends of the stems being provided respectively with controlling arms 65 and 66 to which operating rods 67 and 68 are connected, the rods extending through the dash-board 2 and provided with adjustable stop nuts 69 and 70 for adjusting the lift of the valves. Preferably a connecting bar 71 is secured to the two operating rods 67 and 68 and is providedwith a handle 72, but in some cases the bar may be omitted in order that each feed valve may be operated separately and independently. Each reservoir has a top 73 thereon through which the reservoir is filled, each top having an aperture 7t therein, one top being normally closed by a cover 7 5 having an aperture '76 therein, the other by a cover 77 having an aperture 78. The valve stems extend through the tops and the covers the latwith and heating niitting liquid A 1-10- ape-s,

as to bring the aperthe apertures in the ter may be rotated so tures therein fair with tops of the magazines.

in practical use suitable liquid such as gasolene is carried in the two reservoirs, and when ready to start the engine the operator opens the controlling valves and slightly turns one or both of tie teed valves so as to let av small quantity oi gasolene flow gravity to the lower portion or sag of one or both of the warm-air pipes where the gasolene momentarily remains until the engine produces suction after being cranked or otherwise started. The suction draws air in through the warm-air pipes and the air becomes carbureted by the gasolene while passing through the warm-air pipes to the explosion chambers of the engine, so that the engine at once receives explosive mixture in advance of the practical working of the carbureter, or if the latter has begun to operate the BXPlOSlVQTfilXtHIC: is enriched to a greater extent than that furnished by the carbureter, so that the engine starts promptly. After the engine is governed in the usual manner is usually found that the constituents of the explosive mixture are not accurately proportioned and that usually it is an advantage to supply additional air, and that the air should be heated in order to heatthe' explosive mixture and thereby produce most eilicient mixture, it is preferable that the controlling valves he closed after starting the engine and until it is desirable or expedient to dilute the explosive miXture, and then it is only necessary to manipulate the operating rod to open the controlling valves more or less as may be found best on observation of the results attained, the admission of the heated air and its mixing the explosive mixture invariably resulting in increased speed of the engine. It the increase of speed is not desired then the amount of gasolene fed to the carburetor may be reduced and saved.
